I manor or name BQOTS Specification of Letters Patent.

Patented June 20, 1916.

Application filed February 8,1918. Serial No. 747,017.

To all whom it may concern:

Be it known that I, PETER A. Oouren, a citizen of the United States, residing at Boston, in the county of Sufi'olk. and State of Massachusetts, have invented new and useful Improvements in the Method of Making Boots and Shoes, of which the following is a specification.

This invention relates to-new anduseful improvements in the method of making boots and shoes and applies more particularly to the type of boot or shoe in which metallic fasteners are employed to secure either an outer sole and an upper or a welt and an upper to an insole. When metallic fasteners are used the common practice is to drive said metallic fasteners through said welt, through said upper and entirely through said insole with the ends of said fasteners being clenched in the upper surface thereof against a horn. This method however is objectionable for the reason that it leaves said fasteners exposed upon the inside of the shoe, destroying the resiliency of the leather and rendering theshoe extremely uncomfortable for the one who has to wear the same.

The object of the invention is to provide a method for producing a boot or shoe which includes the insertion and fitting of a metal plate into a specially prepared recess formed in the insole of the shoe.

The invention consists in the method of making the same, as set forth in the following specification and particularly pointed out in the claims.

Referring to the drawing: Figure 1 is a transverse section taken through the forepart of a shoe embodying my invention, a portion of said section illustrating the insole tacked to a last and with the clench plate shown in the channel of said insole while the remaining portion shows the last and clench plate removed. Fig. 2'is a detail section taken on line 2, 2 of. Fig. 1 illustrating the preferred method of securing the welt to the insole, said securing means being shown in elevation, portions of the shoe being broken away to save space in the drawings. Fig. 3 is a plan view of an insole constructed in accordance with my invention with the means for clenching the metallic fasteners shown in connection therewith, parts of said insole being broken away to more clearly illustrate the same. Fig. 4 is a detail plan view of the clench plate.

5 is a section, partly in elevation, taken on hne 5, 5 of Fig. 4. Fig. 6 is a transverse section through one side of the forepart of a shoe embodying another form of my invention.

Like numerals refer to like parts through 3 out the several views of the drawings.

In the drawings, 10 is the insole of a boot or shoe to which is secured an upper 11 and a welt 12, while to said welt an outer sole 13 is fastened by means of stitches 14 in the usual manner. The. upper 11 is preferably secured to said insole 10 by metallic fasteners 15 which may be'staples, tacks or any other suitable means extending throu h said upper and partly through said ins le and clenched therein at a substantial distance below the upper surface 16 thereof, while the welt 12 is secured to said insole by another set of metallic fasteners 17 which preferably extend through said welt, through said upper and partly through said insole and are clenched therein, said latter fastening means preferably consisting of staples 18, see Fig. 2.

To facilitate the clenching of the metallic fasteners 15 and 12' below thesurface 16 of said insole I have provided therein a channel consisting of a slit 19 which is formed by splitting said insole from its outer edge inwardly substantially therearound, although preferably said channel terminates at points 20 and 21 adjacent to the extremity of the toe of said insole as beyond this point the metallic fasteners may be driven entirely through said insole without interfering with the foot, either method being within the scope of my invention. At the shank and forepart of said insole the slit 19 extends only part way thereacross and is inclined relatively to the upper and lower surfaces of said insole, see Fig. :1,

while at the heel portion of said insole said slit extends entirely across, as indicated by 1 theline 22, thus forming lips 23 and 24 between which said fasteners may be clenched in a manner hereinafter described.

In Figs. 3, 4 and 5 I have illustrated a clench plate 25 which preferably consists of 105 a heel plate 26, which is adapted to fitthe heel portionof said channel, while extending forwardly from saidplate and pivotally connected at 27 and 28 are metallic strips 29 and 30 which are adapted to fit the narrow portion of the channel which extends along the shank 31 and forepart 32 of said insole.

The strips 29 and 30 are preferably resilient and of suitable hardness to resist being punctured by said metallic fasteners.

In Fig. 6, which illustrates another form of shoe, the insole 37 is substantially identical with those illustrated in Fig. l, the upper 38 being secured thereto by metallic fastening means, preferably tacks 39, which extend through said upper and partly through said insole, while a piece of sheet material which may be a Welt, but preferably an outer sole 40 is secured to said insole by an independent set of metallic fastening means preferably staples 41, which extend through said outer sole, through said upper and partly through said insole, both said fasteners being clenched in said insole substair tially below the upper surface thereof.

The method of constructing the boot or shoe particularly'as illustrated in Figs. 1 and 2 is as follows: Theinsole l0 and the clench plate 25 are first placed together, as in Fig. 3, with the heel plate 26 engaging the heel portion of the channel 19. The strips 29 and 30 are then swung inwardly from the outer positions illustrated in dotted lines, Fig. 3, until they engage the bottoms of the channel 19; said sole is then placed upon a last 44, see Fig. 1, and secured in any suitable manner, preferably by driving a tack 45 through the fore part of said insole and another through the hole 42 in the heel plate 26 of said clenching plate. The upper 11 is then lasted over said insole and secured thereto by metallic fasteners 15 which are driven through said upper and partly through said insole, that is, through the lower lip 24 of said insole and against the clenching strips 29 and 30, whereupon said fasteners are clenched therein. The welt 12 is then placed upon the upper 11 and secured to said insole 10 by means of metallic fasteners 17 which are preferably staples, said staples being driven through said welt, through said upper and the lower lip of said insole against said clenching strips 29 and 30, whereupon said staples are clenched in said insole at a distance below the upper surface 16 thereof. After filling the recess between the inner edges of the welt upon opposite sides of the shoe with any suitable composition 43, the outer sole 13 is then secured to the welt 12 preferably by stitches 14. The last is then removed from the boot or shoe and the clench plate 25 being of a resilient nature is readily withdrawn by insorting a hook through the hole 42 in the heel plate thereof, thus leaving the inner or upper surface of the insole perfectly smooth and of suflicient thickness to retain its resiliency. If desired, after the clench plate has been removed the lip 23 may be cemented to the lip 24 thus completely sealing the channel 19.

In Fig. 6 the upper 38 is secured to the insole 37 by one set of metallic fasteners which are clenched against the clenching plate, while a separate set of fasteners, preferably staples, are provided to secure the outer-sole 40 to said upper and said insole by clenching the same against said clench Iii nation and therefore will better facilitate the removal of the clenching plate upon the completion of the operations hereinbefore stated.

Having thus described my invention, what I claim and desire by Letters Patent to secure is:

' 1. The herein described method of making a boot or shoe which consists in first providing an insole having a channel formed by splitting said insole around the edge, said channel extending inwardly atthe heel'por tion of said insole substantially the depth of said heel portion, then inserting a metallic plate into the heel portion of said channei to substantially fill the same, said plate having forwardly extending metallic strips pivotally connected thereto, adapted to 00- cupy the portion of said channel extending along the sides of the shank and fore part of said insole, then inserting said strips in such portion of said channel, then temporarily securing said insole to a last, then last- U ing an upper over said insole and securing the same to said insole by driving metallic fasteners through said upper and into said insole, and clenching the same against said metaliic strips, then securing a piece of sheet material to said insole by metallic fasteners extending through said upper and into said insole and clenching said fasten ers against said metallic strips, then removing said last, and subsequently removing said plate and said strips from said channel.

2.. The herein described method of making a boot or shoe which consists in first providing an insole having a channel formed by splitting said insole around the edge, said channel extending inwardly at the heel portion of said insole substantially the depth of said heel portion, then inserting a metallic plate into the heel portion of said channel to substantially fill the same, said plate having forwardly extending resilient metallic strips adapted to occupy the portion of said channel extending along the sides of the shank and fore part of said insole, then inserting said strips in such portion of said channel, then temporarily securing said insole to a last, then lasting an upper over said insole and securing the same to said insole by driving metallic fasteners 5 through said upper and into said insole, and clenching the same against said metallic strips, then securing a piece of sheet'material to said insole by metallic fasteners extending through said up r and into said 10 insole and clenching sald fasteners against said metallic strips, remoi'ing said last, and subsequently removing saidplate and said strips from said channel.

In testimony whereof Ihave hereunto set my hand in presence. of two subscribing 1 w1tnesse's. J; i
